I own a couple of 4.5x14 Buckmaster scopes. One of them (attached to a .257 Roberts) was purchased about three years ago, and the lenses inside have come loose and are sliding around. It was fine when it was put in the safe last year but when I pulled it out last week it rattled. When you try to look through it all you see is the edge of a lens lying sideways.
It will be sent back to Nikon for repair soon.
Thank goodness I checked it now, several months before antelope season. These are normally good scopes, it must have been a rare lemon.
